TWRNIF — Transmitter Warning Interrupt Flag
RERRIF — Receiver Error Passive Interrupt Flag
TERRIF — Transmitter Error Passive Interrupt Flag
BOFFIF — Bus-Off Interrupt Flag
1. Condition to set the flag: TWRNIF = (96 ð TEC) & RERRIF & TERRIF & BOFFIF
2. Condition to set the flag: RERRIF = (127 ð REC ð 255) & BOFFIF
3. Condition to set the flag: TERRIF = (128 ð TEC ð 255) & BOFFIF
This flag is set when the MSCAN08 goes into warning status due to
the transmit error counter (TEC) exceeding 96 and neither one of the
error interrupt flags or the bus-off interrupt flag is set
an error interrupt is pending while this flag is set.
This flag is set when the MSCAN08 goes into error passive status due
to the receive error counter exceeding 127 and the bus-off interrupt
flag is not set
flag is set.
This flag is set when the MSCAN08 goes into error passive status due
to the Transmit Error counter exceeding 127 and the Bus-off interrupt
flag is not set
flag is set.
This flag is set when the MSCAN08 goes into bus-off status, due to
the transmit error counter exceeding 255. It cannot be cleared before
the MSCAN08 has monitored 128 times 11 consecutive ‘recessive’
bits on the bus. If not masked, an Error interrupt is pending while this
flag is set.
1 = MSCAN08 has gone into transmitter warning status.
0 = No transmitter warning status has been reached.
1 = MSCAN08 has gone into receiver error passive status.
0 = No receiver error passive status has been reached.
1 = MSCAN08 went into transmit error passive status.
0 = No transmit error passive status has been reached.
1 = MSCAN08has gone into bus-off status.
0 = No bus-off status has bee reached.
